To all whom t may concern; y

Be it known that i, HENRY Renske, a citizen of the UnitedStates, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Ap paratus for Degreasing Substances, of which the following is a specification.

My invention consists in a novel apparatus 1 4lwith which lf promote the eiciency of naph tha or other material with like property in the extracting or grease from substances.

Figurev 1 represents a vertical sectionalV View ci a degreasing apparatus embodying my invention. Fig. 2 represents a plan view thereof. Fig. 3 represents a plan view of the upper portion of the operating-tank with portions of the device removed. Fig. 4 represents an elevation slowing the operating means in detached position. Fig. 5 represents a plan view oi the gears employed. Figs. 6 and 7 represent sectional views of'a -valve employed, showing the same in diilerent position.

Similar numerals of referenceindicate cor reslponding parte in the figures.

' eferring to the drawings, i designates an open operating-tank which is supported'in -any convenient manner, in the present in- .portion oi the tank, having an o ening 7 therethrough, while the lower wal [of said tank is provided with the extension 3, which supports the bearing 9, through which passes the shaft 10, the latter having a gear 11 thereon meshing with the gear 12, carried by the shaft 13, which is suitably supported and to -.which power is supplied lin any convenient manner. On the bearing 9 is rigidly secured the beveledgear 14, which is in mesh with the gears 15, suitably supported and carried by the shaft 10, said gears having pins 16 and 17 thereon, with which are connected the rods 18 and 19, the latter extending upwardly through the'opening 7 and being connected With pins 20ind 21, carried by the wheels 22, the latter being supported on the shaft 23,

`rods are the drums 26, beyond which are the adjustable collars 27, so that the osition of the drums 26 can be adjusted on t e rods .18 and 19.

23 designates rods which are adapted. to be inserted in the openings on the drums 26 and serve as a support for the substances to be treated'.l

29 designates a steam-jacket, which in the present instance is placed beneath the tank, to which steam is supplied through a pi e 30, asuitable vent or escape 31 being rovidp the jacket, it' being understoo that said jacket can be of any size and laced at any suitable point adjacent the tan 1. Steam 1s conducted to the pipe 30 through the pipe 32, which leads from any suitable source ofsuply and is rovided with a suitable valve 33 or controlling the same. Situated between the inlet of the pipe 32 and the outlet of the pipe 3() is a valve 34 in said pipe, said valve sing oi" anyidesired form and in the present instance consisting of a casing 35, having an opening 36 therein. Within said casing 35 is a valve 37, having ports adapted to register at the proper time with said openings 36 in the casing 35. Connected with said valve 37 is a rod 33, carrying an adjustinglweight 39 and connected with an arm 40, carrying a plunger 41, the latter being situated and moved for able ina casing 42, around which is the 'acket 43, forming a chamber therebetween w ich is in communication With the interior of the tank l by means of the pipes 44 and 45. Situated within the casing 42 beneath the plunger is a column of mercury 46, so that said plunger 41 is actuated by expansion'and contraction of said mercury 46. Connected with vthe steam-inlet 32 is a ipe 47 being provided with a suitable va.ve 48 and having two branches 49 and 50, communicating, respec tively, with the periphery of the turbine 51, so that steam is supplied thereto, either at its axis or its periphery, in order to rotate the same in either a right or left direction. Con. nected with the turbine is a shaf t 52, which is mounted in a suitable bearing and is provided with a gear 53, which meshes with the gear 54, with which is suitably connected a fan 55m, the support for said gear 54 and fan being upon the bar 5, said fan being so situated asA to rotate directly over the opening 4 in the top of the tank.

56 designates a hood which covers the opening 4, and in which hood said fan 55 rotates, the upper portion of said hood being connected by a pipe 57, which communicates with the interior'of a heater 58, same consisting of a suitable casing in which are mounted the heating-coils 59, steam for which issupplied through the pipe 60, connected with the steam-inlet 32, and which is provided with a suitable valve 61 for controlling the steam to the coil 59, a suitable outlet for said steam being provided by the pipe 62. From 1the upper portion of said heater 58 leads a pipe 63, which communicates with the interior of the condenser 64, the latter havin a water-jacket 65 therearound andwhic ends, so that the vapors from the heater 58 pass around these pipes, and l providebaflieplates 71 on the interior of the condenser in.

order to give a greater path of travely'for the vapor in the condenser. The left bathe-plate is provided with holes at its lower portion to permit the liquid from the last compartment to reach the outflow 74.

72 desi nates a vent-pipe which allows thel outflow o the liquid Jfrom the tank 64 whenever the valves in connection therewith and for the purpose hereinafter described are operated.

The liquid from the tank 64 can be guided into the storagetank 7 8 through the pipes 74 and 7 6, and from the tank 78 it maybe car-y ried into the vessel 1 by means of pipe 77, the valve being then closed. If for some reason the communication withv the storage- 4tank 78 should be interrupted, the liquid from the tank 64 maybe directly guided into the vessel 1 by opening the valve 75 and closing the valves in thepips- 7,6 and 77. From the bottom part of the vessel 1 leads a pipe 73 into the tank 64 for the purpose of conducting up the remainin vapor for li uefaction, as will more `fully e described ereinafter. i

The operation is as follows: The substance is placed upon the arms 28 and is submerged by the degreasing material-such as, for instance, naphtha. A sufficient time, according to the nature of the substance, is given the naphtha l to soak the substance, after which heat is appliedby passing steam into the jacket 29 and placing the weight oi' the temperature-valve to the proper point. At this same time power is furnished to the turbine 51 in' order ,to rotate the fan'55'in such a direction as to draw off the vapor romthe vessel as fast as-it is generated and to carry it through the hood 56, pipe 57, heater 58,

and pipel 63 into the condenser 64, wherein it becomes liquid. .Saidliquidisthenpermitted` by the open vent 7 2 to escape through the.

pipes 74and 76 into the storage-tank 78, the I valve 75 and the valve in the pipe 77 being closed. When by evaporation the surface line of the naphtha has reached a point below the substance, the mixture of naphtha and grease is carried off through the pipe 79 and z time? the naphtha is withdrawn yagain' through the pipe 79, and the remaining va por .is drivenI up through the pipe 7 3 intothe cooler 64 for liquefaction by reversing the action of the turbine; 51 and ian. 55. Said ner employed during the actual degreasing process; but as the resh naphtha supplied for the scouring leaves cooler gases behind which have more the natural tendency to dey scend than to ascend it is deemed more prac tical to drive them out through the pipe 73.

After all this has been accomplished the` substance is withdrawn from the vessel 1 through the door 3. The purpose of carrying the vapor drawn from the vessel during the actual degreasin process on its way to the cooler through a heater is to keep the va- Fresh naphtha is then supplied t'o vvapor could perhaps be drawn ofi in the inan- IOOA por as a vapor until it reaches the cooler;

otherwise and in the event the pes 63 should necessarily be carried to a distance making up and down bends, Sco., a portion of the vapor would liquefy, iilling up low points -ofthe conduit, forming traps, and preventing further passage of thevapor. The heater as well as the fan force are therefore essential.

The'diilerence of operation with this apparatus in comparison with former is that in the former the vapor of the naphtha remains in the operation-tank, and therefore limits the evaporation, so as to leavethe substance submerged until the liquid is drained-off. 1n this draining offthe surfaceline of 'the liquid falls from the top part of the substance'- to below, but this is for no other purpose and with no other eilect but to drain 0H, and it is deemed profitable to accomplish this re moval as rapidly as possible to gain time. In my operation the vapor is constantly withg IIC drawn by force, thus avoiding pressure and promotin' evaporation, the surface line ci the liqui lowering constantly andl slowly imm too L0 lieow in orer *'50 subject every part of h substance to the higher acion of 'she' iqui" at its Surface line, which is deemed bhe most socviont point o'r" action.
